Mr Trump's warm words will be welcomed by Downing Street after so much of the spotlight falling on his relationship with former UKIP leader Nigel Farage.

A date for the meeting is yet to be revealed, but it is expected to come within weeks of Mr Trump's inauguration on January 20.

May will be pleased to see Trump so soon after he is sworn in to the White House – after she was pipped to speaking with the tycoon following his election by the leaders of nearly a dozen countries.

The pair are understood to have spoken twice since his victory in November, with the PM suggesting key staff meet to lay the groundwork for a visit.
